This invention relates to conveyers of the shaker type. The main object of the invention is to provide, in connection with such conveyers, improved means whereby the material at the discharge end may be loaded into tubs, or trams, or raised above the level of the conveyer.

It is well known that the shaker type of conveyer does not as a rule operate satisfactorily against a gradient. According to the present invention a loader or elevator (hereinafter referred to simply as al loader) is driven direct from the shaker conveyer, the shaker motion being converted vinto unidirectional motion.

The invention further includes the im-I proved features, combinations and arrangements embodied in the preferred form illustrated by the accompanying drawings, where- 1n Figure lis a side elevation.

Figure 2 a plan, and

Figure 3 an end view.

As illustrated, the loader takes the form of a trough continuation l provided with a belt 2 of rubber, wire, mat or similar material, on to which the material is discharged by the shaker motion. The belt 2 may be of the endless type mounted on pulleys or drums 3, 3a carried beneath each end of the trough. The trough is pivotally connected at 4 so that it may be lowered or raised to the required extent. The driving of the belt is accomplished by reversed ratchet or equivalent mechanisms operating upon the driving pulley in such a way that the reciprocating motion of the shaker conveyer gives a motion to the belt in a forward direction, on both the forward and backward stroke. T his may conveniently be carried out by providing a pair of drums 5 each carrying a pawl 6 for engaging corresponding ratchets 7 upon the axle 8 of the driving drum 3a. One drum 5 may be carried upon each side of the trough and a pair of fixed driving chains 9 or their equivalent, lying longitudinally one on each side of the trough, drive the drums owing to the bodily reciprocating motion of the latter. Both ends of these chains 9 may be simply fixed to some stationary obj ect.

The chains 9,1naypass round the-drums 5 i in Y opposite directionsgso g:that ,the latter grevolve.accordingly-at each stroke; thus Y:while one pawlgis' driving itsL ratchetgthe other; is

l. The combination of a; Shakerconveyer, including a frame supported ffor shaker movement, .a load-,carrying element movable longitudinally of the shaker ,conveyerand relatively reversedy ratchet devices. controlling ,the movement of, .the ,load-carrying, element and operated in both relatively-opposite ,shaker movementsfto compel a vlunidirectional independent motion of-the load-carrying element.

2. The combination of a shaker conveyer including a delivery section, a load-carrying belt forming a part of the shaker conveyer delivery path and having its adjacent ends directly connected and moving with the delivery section, means for driving the loadcarrying belt, and means operated in the respective shaking motions of the conveyer to actuate the belt driving means to impart a uni-directional movement to the belt independently of the direction of movement of the delivery section of the shaker conveyer.

3. The combination of a shaker conveyer including a movably connected delivery section, a load-carrying belt cooperating with the delivery section, driving means for the belt, operating means for the belt, relatively lGo Y v2v p y 1,843,042

A loader forming part of a shaker conve yer and including an endless belt, a driving pulleyfor the belt, fixed operating members,

and connections intermediate the fixed operating members and driving pulley whereby p in all shaker movements of the loader a unii directional movement is imparted` to the pul- I ley to thereby independently operate the belt continuously in'one direction. i

5. A shaker conveye'r including a loader section,-an endless belt forming part of saidV loader section, a pulley for driving the belt,

oscillating members arranged beyond the pulley, `fixed members 'engaging said oscillating ymember-s and operatingthe same in relative` ly reverse directions in the shaker movements of' the loader, and pawl and ratchet mecha-y nism inter-mediater theaoscillating members and pulleyy to conve-rt the relatively opposite movement of the oscillating members into a uni-directional driving force on the pulley and thereby the'belt." f -K I l 6.
